It's alarming that it [Zephyr] has been a desert for decades. It is kind of amazing to finally see action.

The design is now complete and EPA and MDEQ now have a signed project agreement. The two agencies are waiting for the wetlands permit to be finalized and approved before the project can go out for bid. A cleanup will begin no earlier than spring 2017.
Sediment to remediate: 36,000 to 45,000 cubic yards
Contaminants: Total petroleum hydrocarbons, lead and other heavy metals
Method: (Relatively) dry excavation
When: 2017, 1.5 years expected duration, including habitat restoration
Partners: U.S. Environmental Protection Agency and Michigan Department of Environmental Quality
Notes: A small portion (about 1,400 cubic yards) has been characterized as hazardous for lead and will be stabilized to non-hazardous conditions before removal.
Cleanup at the Zephyr site is located in the wetlands of the former Zephyr Oil refinery just south of Holton Rd. (M120) and east of the railroad tracks. See yellow area in figure below. MDEQ is conducting additional cleanup efforts in the upland portion of the site in collaboration with the US Army Corps of Engineers.
The project design is complete, and a cleanup could begin fall/winter 2016. More technical information will be provided once it's available.
